LIQUIFJ-COATING MACHINE.

Specification of Letters Patent.

Patented Flay 11, 1909.

Application filed January 28, 1907. Serial No. 352.560.

To (ZZZ whom it may concern:

Be it known that I, Harm A. BEAUSEJOCR, a subject of the Crown of Great Britain, and resident of the borounzr of Brooklyn, in the h V city and State of New 1' ork, iavo invented a i new and useful Improvement no Liquid- Coating Machines, of which the following is a spec fication.

i invention relates to machines for ap plying a coat of liquid to an article and has for its principal object to produce a macl'iine that will give a more even coating of the liquid to the article heing treated and will prevent what is known in the art as lapping or double coating of the article.

A further obiect is to provide a machine which will be cheap, durable and simply constructed and which can he easily operated either by hand or power.

The machine is also so arranged that the article being coated will be kept free from dust while dryingand the c a liquid will be screened at every operation, thus keeping the liquid clean so that-it may be used repeatedly.

A practical embodiment of my invention is represented in the accompanying drawings in which- Figure 1 is a view in side elevation partially in section, of a macl'iinc suitable for carrying: out my invention, Fig. 2 is a front view of the same partially in section, and

taken in the 2, looking in.

Fig: is a transverse section plane of the line A--Pr of Fig. the direction of the arrows.

in the accompanying drawings have siown a device consisting of two tanks arranged to be alternately used for coating the articles to be treated. As these tanks are similar in construction I will proceed to describe one only of said tanks.

The tank for recei' cg the article or articlcs to be treated. is denoted b 1 and it is in the present instance, made rectangular in form. The cover for the tank is denoted by and it may rest loosely on the open top of the tank or may be secured thereto by any suitable means if so desired. This cover 2 is the tank, with a V-shaped pocket 3, the side of the pocket adjacent to the side wall of the tank being provided with a fine mesh screen 4 through which the coating liquid may flow into the tank. This pocket 3 and screen 4 are so placed that When the coating liquid poured into the tank, it will be directed 2IP"tiDSt the side wall of the tank and not a inst the article or articles to be coated.

The means which l have shown for withdrawing the coating; liquid from the tank after the article has been treated comprises a series of spigots 5 having suitable cocks 6.

Means are provided for securing the article rigidly within the tank, which means in the present instance is shown. as comprising a swinging clamp member 7 and a stationary clamp member 8 arranged to co-act thorc with. This swinging clamp member 7 is operated from the exterior of the tank by means of a hand screw 9 arranged in position to have its inner end engaged with the free end of the swinging clamp member. Means are provided for spacing the article to be treated above the bottom of the tank, which means are shown as comprising two serrated ribs 16, 11. For supporting, raising and lowering the tank I provide a cross shaft 1:? which is mount ac in suitable hearings in ln'ackcts 13. On this cross shaft 1 provide pulleys 14-, 15, to which the corresponding upper ends of flexible connections, such as chains, l6, 1.7, are secured, the lower ends of said chains being secured to hangers l8, l9, loose y mounted on pivots 20, 21, fast to the opposite sides of the tank 1. T his arrangement permits the tank to be readily raised and lowered and also to be swung into position for permitting the ready insertion and removal of the articles to he treated. An end chain 22 passes around a sprocket wheel 23 fast on the shaft 12 for permitting the manual handling of the tank.

hen the machine is composed of a plu- 5 rality of tanks, the chains from one tank are wound around their pulleys l i, 15, in one direction and the chains from another tank are wound around their pulleys is, 15, in the opposite direction, so that as one tank is being raised, another tank is being lowered.

Supposing the machine to comprise two tanks as shovm in the accompanying drawings, the operation of the same is as follows.

; The lowered tank is tilted into a position provided, ad acent to one of the side walls of such as that shown in dotted lines in Fig. l, for permitting the ready insertion of the article to be coatedv therein. The tank is then swung into its vertical position and its cover 2, with its pocket and screen, 3 and 4, is placedv in position over the open top of the tank.

is One or more of the cooks 6 of the spigots 5 may then be o3ened to permit the coating liquid which is located in the raised tank, to flow into the pocket 3 and from thence through the screen l into the lowered tank. This 0 oration will permit the liquid to be gradua 1y withdrawn from engagement with the article being treated in the raised tank and simultaneously gradually permitted. to enter the lowered tank to engage the article therein. After the article in the raised tank has become su'tlieiently dry the raised tank may be lowered into position to permit the removal of the article therefrom, the operation of lowering the raised tank serving to. raise'the lowered tank. to bring it into proper position. to iill the other tank with. the coat- Zing liquid after a new article has been in sorted therein.

By this method a very even coating of the article being treated is insured. Furthermore, the thickness ol the coating may be varied by the rapidity with which the liquid is withdrawn from its engagement therewith by opening the required number of spigots. Also the a ticles are protected from dust an d dirt while being dried owing to their being entirely inclosed within the tank during this drying period. Furthermore, the coating liquid is screened thoroughly after every operation, thus permitting the coating liquid to be used repeatedly.

l l hile I have shown and. described two co.

acting tanks, it is to be understood that one or more may be used successively, the object of this invention being to provide means for insuring an even. coating of the article by the insertion and removal of the coating liquid.

W hat I claim is:

1. A tank for holding therein an article to be coated, means arranged to introduce a coating liquid into the top and witudraw it from the bottom of the tank while the article is held in the tank and means permitting the tank to be tilted. for the insertion and removal of the article.

2. A tank for holding therein an article to be coated, a cover for the tank for completely inclosing the article, means arranged to introduce a coating liquid into the top and withdraw it from the bottom of the tank while the article is held in the tank and means permitting the tank to be tilted for troduce a coating liquid into the top and withdraw it from the bottom of the tank while the article is held in the tank and a screen for separating impurities from the liquid while it is being introduced into the tank.

i. A tank for holding therein an article to be coated, a cover for the tank for completely inclosing the article and means arranged to introduce a coating liquid into the top and withdraw it from the bottom of the tank while the article is held in the tank, said cover having a pocket for receiving the liquid as it is introduced into the tank, said pocket having a screen for separating impurities from the said liquid.

5. A tank for holding therein an article to be coated, a cover for the tank for completely inclosing the article, said cover having a pocket provided *ith a screen for receiving the coating liquid as it is introduced into the tank, and one or more spigots for withdrawing the liquid from the tank while the article is held therein.

6. A tank, means for removably holding an article to be coated therein, means arranged to introduce a coating liquid into the top and withdraw it from the bottom of the tank while the article is held therein and Q means permitting the tank to be tilted for the insertion and removal of the article.

7. Tanks for holding therein articles to be coated, means for alternately raising and lowering the tanks, means for withdrawing the coating liquid from the bottom of the raised tank and introducing it into the top oi the lowered tank and means permitting the tanks to be tilted for the insertion. and

removal of the articles.

means permitting the tanks to be tilted for y the insertion. and removal of the articles.

In testimony, that 1 claim the foregoing as my invention, 1 have signed my name in presence of two witnesses, this 15th day of January, 1907.
